目的 观察蜂蜇伤致横纹肌溶解的MRI表现，探讨MRI对蜂蜇伤致横纹肌溶解症的诊断价值。 方法 收集2008年9月-2009年12月急诊科及肾内科蜂蜇伤患者4例。对其行蜇伤部位MR增强扫描，对其中1例患者行远离部位肢体扫描。总结MRI征象，评价MRI在蜂蜇伤所致横纹肌溶解临床诊治中的作用。 结果 蜇伤部位显示T1WI稍低，T2WI高信号影像，在T2WI加压脂影像中显示最为清晰，横纹肌损伤有局部随肌间隙扩散趋势，但远端无蜇伤肌肉受累。 结论 蜂蜇伤导致的横纹肌溶解可在MRI影像上得到直观反映。MRI具有良好的软组织对比度，能及时反映横纹肌受累范围及程度、治疗后恢复情况等，可为其临床诊治评估提供有利信息。
Objective To investigate the effect of continuous renal replacement therapy (CRRT) on rhabdomyolysis with acute kidney injury (AKI) following multiple wasp stings. Methods We designed a prospective study which enrolled 132 patients who developed rhabdomyolysis after multiple wasp stings between January 2013 and December 2016 in Jianyang People’s Hospital, West China Hospital of Sichuan University and Anyue People’s Hospital. Among these, 62 patients with AKI were treated with CRRT. The modality of CRRT was continuous veno-venous hemofiltration (CVVH). CVVH was performed for at least 48 hours by using Prismaflex and M100-AN69 hemofilter. Hemofiltration was accomplished using predilution bicarbonate with the replacement fluid rate of 2 000–2 500 mL/h [30–35 mL/(kg·h)]. Heparin or low-molecular-weight heparin was used for anticoagulation, with blood flow rate of 180–200 mL/min. Then intermittent hemodialysis was performed when patients’ condition became stable. Mortality, kidney recovery, biochemical indicators and length of stay were collected. Results Fifty-one patients met the inclusion criteria finally, and four (7.8%) of them died during hospitalization, and the remaining 47 patients survived with completed treatment and follow-up. At 3, 7, and 14 days after treatment, the creatine kinase, myoglobin and lactate dehydrogenase of the patients all decreased significantly and gradually, and returned to normal level finally. Kidney function was recovered in 45 (95.7%) patients within 3 months, and 2 patients suffered chronic kidney disease. The patients’ hemoglobin recovered to normal level at (30.5±11.3) days. Conclusion Rhabdomyolysis and AKI were severe complications following multiple wasp stings, and early CRRT may bring significant benefits to such patients.
Objective To evaluate the efficacy and safety of intermittent hemodialysis (IHD) and continuous renal replacement therapy (CRRT) on patients with acute kidney injury (AKI) after bee sting. Methods A prospective observational analysis was made on patients with AKI after bee sting treated in Jianyang People’s Hospital or West China Hospital of Sichuan University between July 2015 and December 2020. According to different initial renal replacement therapy modes, the patients were divided into IHD group and CRRT group. The IHD group received hemodialysis for 4 hours each time, once a day or 3-5 times a week; the CRRT group used Prismaflex machine for continuous veno-venous hemofiltration or continuous veno-venous hemodiafiltration within 72 hours after admission, for at least 12 hours a day, followed by CRRT or IHD, depending on the patient’s condition. Both groups could be treated with hemoperfusion (HP) and symptomatic support such as glucocorticoid, blood transfusion and fluid rehydration. The IHD group was divided into IHD subgroup and IHD+HP subgroup, and the CRRT group was divided into CRRT subgroup and CRRT+HP subgroup according to whether renal replacement therapy was combined with HP. The basic information of patients and clinical laboratory examination results were collected, and the renal function recovery and mortality rates of patients in the two groups were compared, as well as the changes of laboratory indicators. Results A total of 106 patients were enrolled, 50 in the IHD group and 56 in the CRRT group. There was no statistical difference in the rate of complete renal function recovery 30, 60, or 90 days after treatment between the two groups (28.2% vs. 31.2%, P=0.758; 46.2% vs. 50.0%, P=0.721; 82.1% vs. 81.2%, P=0.924). But in the CRRT subgroup analysis, there was a statistical difference in the 30-day renal function recovery rate of CRRT+HP patients compared with CRRT alone (47.6% vs. 18.5%, P=0.031), while no statistical difference was found in the IHD subgroup analysis. After 3 days of treatment, the levels of creatine kinase of the IHD+HP subgroup and the CRRT+HP subgroup were lower than those in the IHD and CRRT subgroups, and the differences were statistically significant [(7875±6871) vs. (15157±8546) U/L, P=0.026; (10002±8256) vs. (14498±10362) U/L, P=0.032]. There was no statistical difference in 30-day mortality or incidence of serious adverse reactions between the two groups (P>0.05). Conclusions There is no obvious difference in improving renal prognosis or reducing mortality between CRRT and IHD for patients with AKI after bee sting. However, CRRT combined with HP therapy could shorten the recovery time of renal function and increase the 30-day kidney recovery rate. HP may contribute to early renal function recovery in patients with AKI after bee sting, but more high-quality randomized controlled trials are needed to further confirm this.
Severe bee stings can trigger a systemic inflammatory response and multi-organ dysfunction, potentially resulting in fatality. Acute kidney injury (AKI) is a frequent complication in patients with severe bee stings, and conventional comprehensive treatment combined with various blood purification therapies is commonly employed in clinical practice to promptly manage the condition and reduce the average hospital stay duration. This article primarily delves into the significance of enhanced clinical nursing care for patients with bee stings-induced AKI undergoing blood purification therapy. Specifically, it underscores the importance of patient education regarding treatment-related considerations, nursing techniques for vascular access during treatment, potential complications, and corresponding nursing interventions.
